Description

The sun beetle comes in nine subspecies, the three common ones are: Pachnoda marginata aurantia, Pachnoda marginata marginata, Pachnoda marginata peregrina, with ranging colors. Pachnoda marginata aurantia comes from orange to a yellow-orange, some having a hue gradient towards the middle seen in diagram below. Pachnoda marginata marginata normally is red or crimson with little change between individuals. Pachnoda marginata peregrina, the more common amongst the subspecies, is a pale yellow or orange with brown spots; one spot being on the thorax

 on each wing.

Sometimes the spots on the elytra are almost unnoticeable, as they seem to blend in with the rest of the body, this can be seen in the picture on the bottom left of Pachnoda marginata peregrina in the terrarium under "As pets".

The larvae of the pachnoda can make a low snore-like noise when making his cocoon.

Life cycle

After mating, the female lays an egg
Egg (biology)
An egg is an organic vessel in which an embryo first begins to develop. In most birds, reptiles, insects, molluscs, fish, and monotremes, an egg is the zygote, resulting from fertilization of the ovum, which is expelled from the body and permitted to develop outside the body until the developing...

As pets

Pachnoda marginata is an easy beetle to keep, requiring a terrarium with a lid (as it can fly out), a layer of moist ground, something to climb on, a warming lamp and food like bananas, apples and other fruits. The larva
